I think WoSign should chime in and provide clarity about what happened. There's far too many innocent explanations to start crying foul. However, the fact a researcher was able to obtain a cert without proper domain validation is pretty serious. I'd like to hear more details about how this was accomplished. Ports 8080 and 8443 aren't that uncommon so penalizing someone merely for port use seems harsh when there wasn't a policy against it. -----Original Message----- From: Peter Bowen [mailto:pzbo...@gmail.com] Sent: Wednesday, August 24, 2016 10:45 AM To: Gervase Markham <g...@mozilla.org> Cc: Jeremy Rowley <jeremy.row...@digicert.com>; mozilla-dev-security-pol...@lists.mozilla.org; Richard Wang <rich...@wosign.com> Subject: Re: Incidents involving the CA WoSign On Wed, Aug 24, 2016 at 9:30 AM, Gervase Markham <g...@mozilla.org> wrote: > On 24/08/16 17:12, Jeremy Rowley wrote: >> On incident 2, it sounds like they are both using the same >> auto-generation script. > > It seems like a bit more than that, doesn't it?

I think you are missing the most likely option: CA hosting. My understanding is that it is not uncommon that one CA operator contracts with another CA operator to run a CA on behalf of the first operator. I don't think it has been clear what disclosure of this practice is required. Given that I believe this is widespread, I assumed that all of the issuing CAs in this case were operated by the same entity. Thanks, Peter
